How can i make a code about the fixed object's direction ?
I am making a code the enemy character that doesn't move and shoot the ball when the player character was enter the specific range. But, there is a problem that the enemy character can look right and left when player character is more or less than enemy's x position. But the enemy can't look front and back when player character is more or less than enemy's y position. Of course, the enemy's attacking is also applied.

(Green circle is enemy character and black one is player character.) I want that the enemy character look at the direction forward player when the player character enter the specific range like picture. And it's important that the enemy's position is based (For example, the enemy's position is based, the player character entered the right range like right of X shape. )
Of course, I want to make an enemy's action that throwing the ball forward up and down.
